The purpose of this multicenter observational cohort study is to evaluate three-year outcomes in adults who underwent anatomic or reverse total shoulder arthroplasty using a contemporary shoulder implant system. The main questions it aims to answer are: Are three-year patient-reported outcomes after anatomic total shoulder arthroplasty comparable to those after reverse total shoulder arthroplasty? How often do the implants used during surgery differ from the preoperative three-dimensional (3D) surgical plan, and are these differences associated with patient outcomes, complications, or revision surgery? Researchers will compare patient-reported outcomes, function, complications, and revision rates between patients who underwent anatomic and reverse total shoulder arthroplasty. Researchers will review participant existing medical records and surgical information. Participants whose two- or three-year outcome measures are not available may be asked to complete a one-time questionnaire by telephone or secure electronic survey. No treatments or additional clinical procedures will be performed as part of this study.
Contemporary shoulder arthroplasty systems incorporate modular components, updated implant geometry, three-dimensional (3D)-printed technology, and preoperative 3D surgical planning to support patient-specific implant selection and intraoperative decision-making. Although these features are intended to improve procedural efficiency and flexibility, multicenter evidence regarding their clinical performance and associated patient outcomes remains limited. This multicenter observational cohort study will evaluate patients who underwent primary anatomic total shoulder arthroplasty (aTSA) or rever…
